Centrifugal Fans and Blowers typically have one of eight types of wheels that draw the air into the inlet of the blower housing, through the wheel, and discharges it at 90 degrees out through the discharge of the housing. The two most common types of Centrifugal Blowers are Pressure Blowers and Volume Blowers.

Types of Blowers blowerwheel.com. A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower fan, biscuit blower [citation needed], or squirrel-cage fan (because it looks like a hamster wheel)., Centrifugal fans are not positive displacement devices. Centrifugal fans have certain advantages and disadvantages when contrasted with positive-displacement blowers. The centrifugal fan is one of the most widely used fans.
